Abstract
A method of removing pollutants from porous, solid materials uses a biomass loaded onto a support. The biomass is put into contact with a pollutant contaminated porous, solid material so that the bacterial biomass degrades the pollutant. The moisture level of the support and biomass are maintained at a level that optimizes pollutant removal and is a function of the relative solubility of the pollutant.
Claims30
A method of removing pollutants from pores of solid materials, the method comprising:
- loading a biomass able to degrade at least one pollutant to a support;
- and
- contacting the biomass loaded onto the support to a porous, solid material contaminated with at least one pollutant until an amount of removal of the pollutant is achieved.
A method of removing volatile pollutants from a porous, solid surface, the method comprising:
- loading bacterial biomass to a support, the bacterial biomass comprising bacteria able to express enzymes that degrade the pollutants;
- contacting the bacterial biomass loaded onto the support to a porous, solid material contaminated with at least one volatile pollutant until an amount of the pollutant removal is achieved;
- and
- maintaining a moisture level of the bacterial biomass such that removal of the pollutant is optimized.
A method of removing pollutants from pores of solid materials, the method comprising:
- applying biomass, able to degrade at least one pollutant, to a porous, solid material;
- and
- maintaining environmental conditions to sustain pollutant degradation until an amount of pollutant degradation is achieved.
